To all whom it may concern:

Be it known that I, GEORGE H. MILLER, a citizen of the United States, and resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Inking Attachments for Printing-Presses, of which the following is a specification.

v This invention relates to inking attachments for printing'presses and its object is to divide the trough of the fountain into two or more parts, so that different colored inks may be used therein, and to provide a feed roller at one side of the trough which may also be divided to correspond with the divided trough, so that the various inks may be separately fed to a divided vibrator roller and the usual inking rollers for the type, as will be more fullydescribed in the following specification, set forth in the claims and illustrated in the accompanying drawings which form a part of this application, and wherein:

Figure 1. is a plan view of the ink fountain. Fig. 2. is a similar view arranged to distribute two different inks. Fig. 3 is an end View of the fountain. Fig. 4 is across sectional View. Fig. 5 is a plan view of a A modified form; Fig. 6 is a plan view of the fountain partly in section, and arranged to supply three different colored inks. Fig. 7 is a plan view of an ink plate, the fountain and the inking rollers. Figs. 8 and 9 are sectional views of the vibrator roller in different conditions.

In carrying out the objects of this invention, it is necessary to divide the feed roller of a fountain, and at the same time the trough containing the ink, so that the inks to be used may at all times be separated for use on the forms.

The trough 10 of the fountain is of the usual form,.having end pieces 11 and 12 and a feed roller 13 mounted on a shaft 14 and driven from any desired source. The roller is divided into any desired number of parts, the end portion 15 being permanently secured to the shaft, while the section 16 is connected with the shaft by means of a spline 17 which allows the section to shift longitudinally, hilt rotates the same with section 16. One end of the section 16 is fitted in a socket18 of the head 19 of the end 12 and while adapted to move freely therein, is so fitted as to prevent the release of the ink at that end of the roller, but permits of its'passage between the flexible bottom 20 and the roller only. The section 16 being hollow, one end is threaded while the other end is grooved for the, spline 17 and into the threaded end plays a nut 21 loosely carried on the shaft 14,, but locked thereon when desired by the nuts 21 and 22. The

nut 21 has an outer flange 23 fitting against the head 19 and having the handles 24 to turn the nut.

When it is desired'to use two inks in the trough 10 the lock-nut 22 is loosened and the nut 21 turned to the right, drawing the section 16 away from its companion section, and one end into the socket 18 so as to create the opening 25. A partition 26 is inserted in this opening and a spring 27 clamps the latter to the trough while the extension 28 is fitted beneath the shaft 14, making a perfect barrier between the different inks which may be put in the two sections of the trough. The nut 21 then may be turned to secure a perfect though loose joining of the partition and the sections of the roller and the lock nut 22 then be adjusted to hold the larger nut in place.

Figs. 5 and 6 show how a roller may be divided to afford three or more divisions of the trough, and show the roller made in three sections 29, 30 and 31, the former being permanently secured to the shaft while sections 30 and 31 are movable longitudinally but held against independent rotation by the splines 32 and 33 playing in grooves on the inside of the sections. The nut 34 adjusts section 31, having suflicient clearance for the other shifting section, and when the partitions 35 and 36 are put into position the nut then shifts the section 31 until a delicate adjustment of the sections with relation to the partitions is secured, so no ink will leak from one compartment to the other.

In accomplishing the result which is sought, it is necessary to also divide the vibrator roller 37; and distributing roller 38, which are of metal and similar in construction to the feed roller above described. The roller 37 has its shaft 39 mounted in oscillating levers 40 which carry the ink from the feed roller 41 to the distributing rollers 42, by which the ink is delivered to the plate 43 andifinally to the inking rollers 44 for the forms. The rollers 37 and 38 areof metal and as shown in Figs. 8 and 9 are divided. at a central point, one part 45 being solid, while the hollow section 46 moves longitudinally. The shaft 47 has secured to it the collar 48'with a spline 49, the latter playing in a groove 50 of the hollow section, and the outer end of the shaft is threaded to receive a nut 51 adapted to play on the threaded portion 52 of the shaft. The interior of the outer end of the section 46 is threaded and the outside of the nut 51 has corresponding threads so that when the nut is turned the section 46 is moved longitudinally either to separate the sections of the roller or join them as one roller. In order to limit the movement of the nut to a minimum, the threads 53 within the section and on the outside of the nut are of much greater pitch than those on the inside of the nut, and the threads 52 on the shaft being in proportion of one to three or four, so that the outward movement of the nut increases the inward movement of the section 46 with but very few turns of the nut. The outer face of the nut is provided with recesses 54 for a wrench or spanner and the lock-nut 55 retains the adjusting nut 51 in either of its positions.

This arrangement of rollers provides for the use of several colored inks in one fountain and the feed and distribution of the separate colors on the ink plate 43 divided by the groove 43' so that each side of the plate may contain a color. The composition rollers 42 and 44 may remain complete or be divided by a groove like the metal rollers, if found desirable.

It is obvious that other modifications and arrangements of the details may be resorted to without departing from the essential details above described nor the scope of the appended claims.

What I claim is:

1. In an inking attachment, the combination with an ink fountain, of a shaft journaled in the ends thereof, a roller comprising several. sections and carried by the shaft, means at one of the shaft bearings for separating the sections, and partitions adapted to be inserted between the sections when separated.

2. In an inking attachment, the combination with an ink fountain, of a rotating shaft journaled in the ends of the fountain, a

roller on the shaft comprising a perma--- one or more longitudinally shifting sections,

filling blocks, and a nut on a threaded end of the shaft to adjust the shifting sections.

4. In inking attachments, the combination with an ink fountain having a cavity at one end, of a shaft journaled in the ends of the fountain, a secured section of a roller on the shaft, a filling block, a longitudinally shifting section internally threaded at one end and fitting in the cavity, and a nut working in the cavity and the threaded end of the roller section to shift the same.

5. In inking attachments, the combination with an ink fountain having a cavity at one end, of a shaft threaded at one end and journaled in the ends of the fountain, a roller section secured to the shaft, a shifting roller section, a spline connecting the latter with the shaft, a nut on the end of the shaft and whose threads play in threads Within the shifting roller section to adjust it with" in the socket, filling blocks, and lock nuts for the adjusting nut.

Signed at New York, in the county of New York and State of New York, this 7th day of February, A. D. 1915.
